Name: Marbas March Gender: Male First person: I (soft/polite) Occupation: Torture Teacher at Demon School Babyls Rank: Unknown Family: Maru (Sister), Yabashi (Relative) Bloodline Magic: Unknown. A male teacher with semi-long black hair and a visible forehead. Because of his plain appearance, Robin calls him "Jimmy-sensei." He has a timid personality and often panics or gets scared when problems arise, giving off an unreliable impression. However, his subject is surprisingly Torture. According to him, it's because he comes from a family of craftsmen. Contrary to his image, he doesn't undergo a personality shift during torture classes; he maintains a perfectly normal attitude. However, in his first class, he made a joke saying, "We will now begin the torture~," which completely weirded out the students. Outside of class, he looks genuinely happy and smiles when it's time for torture, which creeps out even the other teachers. His bloodline ability hasn't been explicitly stated, but since his relative Yabashi has the ability "Perfect Grasp (Kachikachi)," it is likely something similar. He loves everyone. He is a versatile type who can be both a "top" and a "bottom."
